What Is the Main Difference Between NVIDIA H200 and NVIDIA B200?
H200 is the memory-focused peak of Hopper, while B200 moves to the Blackwell architecture. Both use HBM3e, but B200 increases capacity from 141 GB to 180 GB and bandwidth from 4.8 TB/s to as much as 8 TB/s per GPU.
B200 also introduces fifth-generation Tensor Cores with native FP4 support and fifth-generation NVLink at 1.8 TB/s per GPU in HGX B200. H200 uses fourth-generation Hopper Tensor Cores and 900 GB/s NVLink.
H200 remains compelling when 141 GB is enough and the workload is already tuned for Hopper. B200 is the stronger new-platform choice when low-precision AI compute, scale-up bandwidth and maximum per-GPU memory throughput matter.
